Abstract (en)
[origin: WO02063866A2] A computer program product, apparatus, and method for determining the position of a user device. It includes receiving at the user device a plurality of digital television (DTV) broadcast signals from a plurality of DTV transmitters, determining a pseudo-range between the user device and each DTV transmitter based on the DTV broadcast signals, and determining a position of the user device based on the pseudo-ranges and a location of each of the DTV transmitters. Examples of DTV signals include the American Television Standards Committee (ATSC) signals, the European Telecommunications Standards Institute Digital Video Broadcasting-Terrestrial (DVB-T) signals and the Japanese Integrated Service Digital Broadcasting-Terrestrial (ISDB-T) signals.
